Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595262, here are decompositions:

11 + 31595251 = 31595262
19 + 31595243 = 31595262
43 + 31595219 = 31595262
53 + 31595209 = 31595262
73 + 31595189 = 31595262
89 + 31595173 = 31595262
199 + 31595063 = 31595262
241 + 31595021 = 31595262

Showing the first eight; more decompositions exist.
